3M (Three M) is a maker with absolute reliability.
The selection is so abundant it’s actually inconvenient, and the prices are steep enough that it’s hard to take a chance.
It’s tough to buy tape and then think “oh no, I messed up.”
Let me introduce the tapes we use here at Decoboco.

I think there are many people who can’t get by without this.
3M™ Dual Lock™ Fastener—this also has a rich lineup.
My past favorite was SJ3550J (weak) combined with SJ3551J (strong).
Here’s what I think about the merits and demerits from using it….
• Bonds so strongly = holds really well
• Two pieces stacked are thick (close to 5mm)
• Absorbs some curves and unevenness
• Expensive
Given how convenient it is, the price is unavoidable.
Ideally
• Good judgment in installation
• Easy to peel off
• Thin
would be perfect… When I flip through the catalog,

I found something called 3M Scotch SJ4570 Dual Lock.


Even stacked together, it’s only 2.36mm! That’s really appreciated.
The connection feels “peki peki peki” and is easy to install.
*Because it’s thin, the mushroom height is low, so it can’t absorb curves or unevenness.
*If you’re using it surface-to-surface, it’s very good.

Bond strength for reference.
I don’t think stronger is always better.
• Bond strength that keeps the attached item from falling off
• Thinness
These two things are what matter, I’ve learned from using it.
For those who want to try just a little, we sell it by the meter, which is very convenient.

3M 9708 High-tack double-sided adhesive tape 30mm × 10m, 1 roll
It’s just the right width for ETC antennas and such.
It’s good to have both thin and thick double-sided tapes on hand.
• Thin ones are good for surface-to-surface bonding
• Thick ones absorb curves and unevenness


When I organize things like this… I start wanting other tapes.

3M High-tack double-sided adhesive tape 9720 10mm width × 8m 9720 10 AAD
We use it on cowls and FRP and such. It really doesn’t run out quickly.
Because it’s thick, it has good absorption for curves and unevenness.
At Decoboco we only stock 0.8mm and 2.0mm double-sided tape. Since we rarely use double-sided tape, it never seems to run out…

3M Safety-Walk anti-slip tape type F clear 50mm width × 5m


We use it when installing grips. Until recently we were using something a bit thicker, but this time we switched to the thinnest option.
The merits are
• You can install it without compromising the grip feel.
• No adhesive needed—it’s hygienic
• Work is quick
I hear golf grip tape is good,
racket tape is good,
and so on, but… the problem is adhesive residue on the grip.
If you don’t reuse the grip, it’s fine, but… it’s tricky.


Uses include
• Raising the side stand when the bike is loaded
• The bottom of the bike loading stand
• Shelf bottoms
and so on. It’s surprisingly useful.

Nitto acetate adhesive tape NO.5 19mm × 20m
Once you use this, you might not be able to go back to harness tape.
Merits
• You can cut it straight by hand (like cloth duct tape)
• Matte black looks sophisticated (high-end feel)
• You can cut it by hand even after installation
Demerits
• Doesn’t stretch (not really necessary anyway)
• Being fabric-based, it peels off if it absorbs oil (but that’s true of anything)
For spots that don’t need cable ties, I just bundle them with this.
That way you can cut it by hand, and it looks cleaner without the foreign feel of cable ties.
